Early O G “Original Gangsters” of

Early OG of

I met Tom Hartman in early 1980. He was programming an even older Honeywell Delta system with a control language that used 0 & 1

He had written a weather predictor program in this painful control language, projecting cold days / warm days to implement his Dynamic control strategies that manipulated the mass of large buildings.

I was fascinated and worked with Tom over the next few years, learning the craft while helping invent
better control languages. Tom encouraged me to write for magazines AEE, etc.
Tom always inspired me as a writer and presenter.

I was working as a consultant for BCBC as the original SES started in 1975.

Ben Sun, on the left, was working in San Francisco as a consultant. We met at AHR
Ben was the local ASHRAE president and invited me to speak about our new magazine and direction at the local chapter. This 1999 article was inspired by Ben’s project. Ben has been an amazing fan forever.

We have selected this article to be in our first launch issue because we think it sends us all a wake-up call as to how significant the internet is going to be in the future. Our site is aimed at the Automation of Buildings, and integration with the internet will become just another step.…/addr…/addresses.htm

Thanks to these OG

Tom Hartman was one of our first contributing editors

  • Registered Professional Engineer, Mechanical Engineering in Washington, Oregon, California, and British Columbia Canada.
  • In 1974 developed the Hartman EVS simulation Program Series, one of the first hourly building energy simulation programs.
  • In 1976 developed an innovative approach to HVAC control strategies called Dynamic Control.
  • In 1987 led the development efforts of The Operators’ Control Language (OCL) guideline, a control language guide aimed at improving the performance of Direct Digital Control (DDC) systems.
  • In 1988 released a new VAV control concept called Terminal Regulated Air Volume (TRAV).
  • In 1993 Developed a concept called the “Comfort Utility” as a means of capturing the full benefits and opportunities of the deregulated utility era for both building owners/managers and electric service providers. 
  • In 1995 Refined an integrated approach to chiller plant control that reduces annual cooling energy requirements in commercial buildings to less than 50% of a typical chiller plant utilizing a high efficiency chiller (Chiller Plants).
  • Has lectured advanced technology topics at seminars throughout the world.
  • Consulting editor for Heating/Piping/Air Conditioning magazine.
    Internationally recognized expert in the field of advanced high-performance building operation strategies.

In the mid-1990s This evolved into the first online DDC control Manual that inspired Jane and I to start
